Title (EN) IMPROVED SYSTEM FOR THE OPTICAL READ-OUT OF INFORMATION STORED ON A REFLECTING MEDIUM
(FR) SYSTEME AMELIORE DE LECTURE OPTIQUE D'INFORMATIONS MEMORISEES SUR UN SUPPORT REFLECHISSANT
Abstract: front page image
(EN)The invention relates to a system for the optical read-out of information stored on a reflecting medium, comprising a read device comprising an emission means (Dr) for emitting a read beam (Fr), a means for focusing the read beam onto a read zone of the medium, a means for receiving the light energy reflected by the medium, and a means for processing the signals delivered by the receiving means. The system according to the invention also includes a cleaning device comprising an emission means (DUV; 50, 60) for emitting a cleaning beam (FUV) onto a zone of the support to be cleaned, located upstream of said zone to be read.
(FR)L'invention concerne un systme de lecture optique d'informations mmorises sur un support rflchissant, comprenant un dispositif de lecture comprenant un moyen d'mission (Dr) d'un faisceau de lecture (Fr), un moyen de focalisation du faisceau de lecture sur une zone lire du support, un moyen de rception de l'nergie lumineuse rflchie par le support et un moyen de traitement des signaux fournis par le moyen de rception. Le systme selon l'invention comprend galement un dispositif de nettoyage comprenant un moyen d'mission (DUV; 50, 60) d'un faisceau de nettoyage (FUV) sur une zone nettoyer du support situe en amont de la zone lire.
